QT dispersion as a predictor of long-term mortality in patients with acute myocardial infarction and clinical evidence of heart failure

Conclusion QT dispersion, measured from a routine 12-lead ECG following acute myocardial infarction complicated by heart failure provides independent information regarding the probability of long-term survival. However, the low sensitivity of this electrocardiographic marker limits its usefulness fo...

Description
Summary:Conclusion QT dispersion, measured from a routine 12-lead ECG following acute myocardial infarction complicated by heart failure provides independent information regarding the probability of long-term survival. However, the low sensitivity of this electrocardiographic marker limits its usefulness for risk stratification if used in isolation.
